To further this a bit more, sometimes it is not possible or desirable to use the diagnostics pragma. All of the diagnostics, with full explanation call also be found by reading perldiag.

Simply use perldoc perldiag and search for the error message. It sometimes takes a bit of work to find the precise error due to verbage changes, but it is sometimes faster than rerunning things under the 'use diagnostics'.
